Reuters are reporting that the announcements from Nintendo today haven't done a lot for investor confidence in the 3DS platform, with a five percent drop in share price today, a disappointing dip after they've already suffered post-3DS:

"I don't think the new games will make any difference," said Mitsushige Akino, chief fund manager at Ichiyoshi Investment.

"Nintendo succeeded by pulling in people who weren't gamers and their needs now are no longer being filled by Nintendo, they are happy playing games on their mobile phones," he said.

Hopefully as TGS continues we'll get a better feel for exactly what will be on offer from Nintendo going forward on the 3DS and other platforms.
